UUM-72240
Regression
No
Position Node with Object Space has a wrong value when there are multiple active GameObjects with the same shader
Reproduction steps:
1. Open the attached "ReproProj" project
2. Open the "Assets/DemoScene" scene
3. Observe the three squares in the Scene view
Expected Result: All three squares have 4 colors
Actual Result: Only the square at the (0,0) position has 4 colors
Reproducible with: 2021.3.38f1, 2022.3.28f1, 2023.1.0a10
Not reproducible with: 6000.0.1f1
Fixed in: 2023.1.0a11
Reproducible on: Windows 11 Pro
Not reproducible on: No other environments tested
Note: Sometimes, upon the first launch of the project on a "Not reproducible with" version, the shaders still look as they do in "Reproducible with" versions, however entering the Play mode fixes it. This is more prominent in newer versions

Resolution Note:
This is due to the lack of SRP Batching support in Unity Versions 2022.3 and below, uses dynamic batching instead. Dynamic batching combines the sprites into a single batch / draw call which doesn't preserve the transformation data.
If transformation data is needed in your use case, it will be required to upgrade to Unity 6000.0 or later to have the SRP batcher functionality which will not exhibit this behaviour anymore.
